This is a large (11 1/4") heavy platter or bowl. It has some rust and glaze contractions. I have owned it for about 40 years and purchased it as an antique. Any help will be appreciated.

Looks quite a nice dish , Republic period circa 1910-1920 maybe .
Looks like early republic to me.
The bottom mark says "?? ???? ??", (or "made by Detai Porcelain Store, Peking").
